Subject: ENH: Add SIMD versions of negative

NumPy already has SSE2 versions of `negative`.  Changes here convert that to universal intrinsics so other architectures can benefit.  Previously there was no unroll and SIMD was only used in contiguous cases.  We're now unrolling 4x/2x depending on whether destination is contiguous.  x86 doesn't perform as well for non-contiguous cases here, so we leave previous implementation / fall back to scalar.  Additionally, we've added SIMD versions for ints.
